To all whom it may. concern:

Be it known that I, LOUIS F. a citizen of the United States, sir; in thecity of New York borough of l? autism, in the State of New York, haveinvented certain new and useful Improvements in Apparatiis for MovingPaper-Rolls for Printing-Presses.

My invention relates to that class of printing presses in which theprinh ng is done upon a web of paper drawnfrom a roll and has for itsobject to provide an improved method of supplying the rolls of paper toa printing press and coincidently removing the spindle and core fromwhich the paper has been used without stopping the action of the pressor interrupting the process of printing. This object is accompied byproviding a suitable support or holder to receive the rolls of paperwhich are to be used, suitable mechanism for conveying a roll of paperforward at the proper time to its position for use, suitable'coiiperative mechanism for removing the spindle and core from which thepaper has used, and means for transmitting the motion or the printingpress to the operative mechanism of the attachments.

It is evident that a variety of meal appliances may be used toaccomplish this work, and the purpose desired, besides the peculiar formof construction which I have chosen for the pu ose of -12 my invention,but I believe the device and construction shown, to be the simplest andmost effective arrangement of parts for the accomplishment of thepurpose of this invention.

The mechanism employed is hereinafter fully described and reference ismade to drawings which form a part of the specifications and in whichsimilar letters refer to similar parts throughout the several views.

Figure 1 is a central vertical section of a portion of the frame of a 1;ress, showing my invention attached to'the ame of a printing press andalso with two projecting sup orting frames upon which is shown, in t elower supporting fi'ame, the spindle and core of aroll of paper ready tobe lifted out of its operative position, and the spindle and new roll ofpaper ready to be moved into its operative position; and in the uppersupport frame is shown the spindle and coreof roll of paper which havebeen lifted out of operative position, ands' pindle and new roll ofpaper which have been conveyed .into operative position for printing. Aduplicate of my attachments as shown in this figure is secured to theopposite side scribed and illustrated in this figure, and for allintents and purposes the description is the same. Said attachmentsworking together simultaneously constitute one complete set of myinvenfion. Fig. 2 is a" cross section taken on the line 2-2 of Fig. 1showing in part my invention as it appears secured to opposite sides ofa printing press. Fig. 3 is a detail perspective view of clutchmechanism and means for working the same. Fig. 4 is a. detailedsectional view of lifting bracket with block showing. the dove-tailandspring bolt which hold Slide in position. Fig. 5 IS a detailed viewof the arm with blohk for conveying new roll of paper into hearings inoperative position for p T Referring more particularly to drawingsletter A (see Fig. 1) indicates a part of a. flame of a printing press,to which is attached supporting flames a-a, having suitable a which actas bearings for the spindle w' 'ch carries. the roll of paper when inuse.

2 and 2 represent hearings or journals secured to the frame forsupporting the horizontal screw shaft C.

E is a block having threads on its internal surface to cooperate withthe threads of the screw G by which E is moved forward and backward.

e is an arm movably attached to the block E for ging with spindle p forconvey:- ing the spindle to its position for use into the bearings a.Said arm 6 is so mounted as to be thrown out of the way of anyobstruction when block E is brought back to its starting position byhand wheel 6 D is an upright screw journaled in bearings d and d whichare attached to the press e. The screws and D are cperated by an uprightpower shaft 6, which with the roll of paper P of the frame of the pressdesliding block is driven by cross shaft w and gears 6 3 which shaft andgears are a part of the mechanism of the printing press and transmitmotion to the operative mechanism of the attachments. The upright shaftZ) carries a bevel gear 6 which engages with a corresponding gear 0mounted on hollow shaft 0' which rotates loosely on the front end ofhorizontal screw C.

S is a clutch one part of which is mounted' fixedly on the screw C (seeFig. 3), the other part of the clutch being mounted loosely upon androtated by the hollow shaft 0 by means of a feather 0 whichengages withthe movable part of the clutch. The clutch S (see Fig. 3) is locked bylever L attached to a crcss-rod G to which is keyed an arm 9 whichengages with the clutch. Lever L (see Fig. 3) is held in position byspring bolt Z attached to said lever and fitted into notches onprojecting curved arm H. Screws C and D (see Fig. l) are operatedtogether by means of beveled gears 0 and 03.

0 is a guiding rod attached to the bearings e and 6 block E in properposition when the screw C is revolved. The vertical screw D ro pels ablock F upward or downward. Block F (see Fig. 4) carries an arm f whichis movably mounted thereon so that it may pass any obstruction whilebeing brought back to its starting position. Sliding arm f has a springbolt 7' (see Fig. 4) attached to it so as to hold it in place.

0 (see Fig. l) is a guiding rod passing through block F which guidingrod is held in' bearings 11 and d \Vhen block F is at its proper heightit strikes an automatic clutch throw-out K having a projection k at theupper end, which is in the path of block F.

K is attached at the lower end to g (see Fig. 3) which is keyed to across rod G and serves to throw clutch S out of engagement when the rodK is lifted by the action of the block F.

Z is a notch in arm H which receives the spring bolt 1 when the rod K islifted, and serves to hold the clutch S out of engagement.

P represents the roll P (see Fig. 2)

a short arm assing from the paper e press through into t guide-rollers Nand O.

N is a fixed roller held in a bearing V. O is an adjustable rollercarried by the a in the bearing V and is held 1n an adjustable positionby spring S Having thus described my invention as relates to its, parts,the operation of it may be briefly stated as follows: When a new roll ofpaper is needed, it is placed on the supporting arms a-a, and byhandwheel C the blocks E with their movable arms are brought to theouter side of the spindle while the blocks F with their movable arms andwhich serve to hold the are brought to their positions underneath thespindle' from which the paper has been used. Paste having been appliedto paper P it is now brought forward and connected to the paper of thepreceding roll as it passes around the guiding roller N. Atthe same timeby means of the lever L the clutch S is thrown into position and thescrews which carry the hauling-in and lifting arms are set in motionwhereby the spindle and core from which the paper has been used islifted from its bearings and the new roll of paper is brought forwardinto the bearings from which the spindle of the preceding roll has beenlifted. When the. block F on the upright screw has reached its properposition, it comes into contact with the projection at the upper end ofthe disconnectingrod K whereby the clutch is thrown out of connectionand the motion of the screws cease. \Vhile this operation has beentaking place, the paper on the preceding roll has been broken and thepaper from the newly supplied roll follows through taking the place ofthat from the preceding roll. The spindle and core may now be liftedfrom the arms and removed" from the press. This completes the operationwhich is repeated as often as necessary in keeping the press suppliedwith paper.

-I do not limit my invention to the precise construction shownanddescribed, as many changes might be made to the same without departingfrom the spirit of my invention or sacrificing its chief advantages.
